The first logo used by Jaz was a simple design; strong, block capitals with a slight stylised curl to the tail of the ‘J’, but no other embellishments of any kind. These logo types are found on early products, mainly alarm clocks, which were the timekeeping products that Jaz initially produced after its founding in 1919 (source, official website).
In 1941 the ‘Jaz Bird’ logo was created. During the German occupation of France in WWII, the Jazz music genre was considerably frowned upon due to carrying pro-American influences. However, attempts to censor the spirit of jazz and its influences were thwarted through the use of images of the the “Jaseur” (waxwing in English) bird, a migratory bird about the size of a starling. The Jaz brand used this bird as its logo to symbolise its defiance, and their success was unstoppable. In 1943, the ten millionth unit was produced, and when France was liberated, JAZ was the number one French clockmaker (source). The waxwing ‘Jaz bird’ emblem is one of the most commonly used brand logos.

Competition with the Japanese market began in 1983 with the popularisation of quartz watches in Europe. To promote their brand, Jaz began to advertise their “Made In France” image.

Brand Connections
The decline of JAZ as an individual brand started in 1983 when they were absorbed, along with Yema and Framelec, into a consortium owned by Matra Holdings. Yema had already been producing JAZ branded watches since 1982. The JAZ Paris brand started using Seiko movements, the models of which were then used specifically to target the US market. In 1988, Matra Holdings effectively sold out to Seiko France, forming the new larger consortium, C.G.H. (Compagnie Générale Horlogère). From 1988 onwards, JAZ became just another albeit ostensibly French sub-brand of Seiko (C.G.H), using Hattori quartz movements in their watches, as dictated by their Japanese owners. Hence fortuitously the existence of the JAZ N8 ‘7A38’ (source).
The Seiko watch company had signed on to collaborate with Jaz in 1947, although co-production didn’t start for many years. Seiko worked with Jaz on their popular “Made in Paris” line in the early 1980’s and 1990’s, which were still French made, but with Seiko movements. However, due to the quartz crisis, and cheap competition from Asian products, in 1998 Jaz joined the trend and commissioned most of their supplies for their Jaz Tech quartz line from Asia. For a brief period, budget Disney-themed watches were made under the Seiko “Jaz” and Lorus “Jaz” name for $20-$50, before the Jaz brand partnership was discontinued by Seiko in the late 1990’s (source one; source two).
According to some sources, Lorus (a division of Seiko) was established in 1982, and first started to manufacture the Mickey Mouse watches from 1986 until the late 1990’s, after Seiko was awarded with the license to manufacture Disney Watches in 1986. Apparently it was under the Lorus brand that Jaz produced the Disney watches, rather than the general Seiko brand with which they collaborated in their “Made in Paris” watch line. Jaz was a short lived label under Lorus (source).
